Official: Woman killed outside Capitol building was delusional

WASHINGTON — A woman shot to death by police outside the Capitol building after she tried to drive through barricades outside the White House held the delusional belief that the president was communicating with her, a federal law enforcement official said Friday.

The official had been briefed on the investigation but spoke on condition of anonymity because the person was not authorized to speak publicly about the ongoing investigation.

A harrowing car chase unfolded Thursday after the driver rammed the barricades, briefly shuttering the chambers where federal lawmakers were debating how to end a government shutdown and stirred fresh panic in a city where a gunman two weeks ago killed 12 people.

The driver, 34-year-old Miriam Carey, of Stamford, Connecticut, is believed to have traveled directly to Washington immediately before the car chase, the official said. A 1-year-old girl was in the car, though she avoided serious injury and was taken into protective custody.

Investigators have been interviewing Carey's family about her mental condition, which had been deteriorating over the past 10 months, the official said. The woman had made delusional "expressions about the president in the past" and "believed there was some communications to her," and concerns about her mental health were reported in the last year to Stamford police, the official said.

Carey's mother, Idella Carey, told ABC News on Thursday night that her daughter began suffering from postpartum depression after giving birth to her daughter, Erica, in August 2012.

"A few months later, she got sick," she said. "She was depressed. ... She was hospitalized."

Idella Carey said her daughter had "no history of violence," and she didn't know why she was in Washington on Thursday. She said she thought Carey was taking Erica to a doctor's appointment in Connecticut.

Her sisters say they want to know why she had to die. Amy Carey-Jones said on CNN on Friday there should've been "another way instead of shooting and killing an individual." Valerie Carey says she "did not deserve to have her life cut down."

Connecticut records show Carey had been a licensed dental hygienist since 2009. Records show the license expired on Thursday.

Dr. Brian Evans, a periodontist in Hamden, Connecticut, said Carey worked as a hygienist in his office for about two years before she was fired a year ago. He would not go into detail about the reasons surrounding her departure.

He said Carey had been away from the job for a period after falling down a staircase and suffering a head injury, and she learned she was pregnant during the time she was hospitalized. He said it was a few weeks after she returned to the office that she was fired.

Police said there appeared to be no direct link to terrorism, and there was no indication the woman was even armed. Capitol Police Chief Kim Dine, whose officers have been working without pay as a result of the shutdown, called it an "isolated, singular matter."

Still, tourists, congressional staff and even some senators watched anxiously as a caravan of law enforcement vehicles chased a black Infiniti with Connecticut license plates down Constitution Avenue outside the Capitol and as officers with high-powered firearms canvassed the area. The House of Representatives and Senate both abruptly suspended business, a lawmaker's speech cut off in mid-sentence, as the Capitol Police broadcast a message over its emergency radio system telling people to stay in place and move away from the windows.

The woman's car at one point had been surrounded by police cars and she managed to escape, careening around a traffic circle and past the north side of the Capitol. Video shot by a TV cameraman showed police pointing firearms at her car before she rammed a Secret Service vehicle and continued driving. Metropolitan Police Chief Cathy Lanier said police shot and killed her a block northeast of the historic building.

In Connecticut, the FBI served a search warrant in connection with the investigation and police cordoned off a condominium building and the surrounding neighborhood in the shoreline city.

Jackson said Carey was upset earlier this summer when the tires were stolen off her car, but she said her neighbor seemed content. She said she never heard her say anything political.

Carey had been sued by her condominium association for failure to pay fees, court records show. A lawsuit settled in February alleged that she owed the association $1,759 in addition to collection costs, and indicates that she took out a mortgage on her condo in the amount of $237,616.

The chain of events in Washington began when the woman sped onto a driveway leading to the White House, over a set of barricades. When the driver couldn't get through a second barrier, she spun the car in the opposite direction, flipping a Secret Service officer over the hood of the car as she sped away, said B.J. Campbell, a tourist from Portland, Oregon.

Then the chase began.

One Secret Service member and a 23-year veteran of the Capitol Police were injured. Officials said they are in good condition and expected to recover.

Congressman Michael McCaul, who said he was briefed by the Homeland Security Department, said he did not think the woman was armed. "There was no return fire," he said.
